FREDERICK O. LELAND AND SAMUEL W. POLAND, OF LOWELL, MASS.

IMPROVEM ENT IN DEPU RATO RS.

Specification forming part of Letters Patent No. 113,536, dated April11, 1871.

To all whom it may concern:

`Be it known that we, FREDERICK C. LE- LAND and SAMUEL W.PoLAND, both ofLowell, in the county of Middlesex and State of Massachusetts, haveinvented certain new and useful Improvements in Apparatus and Processfor Treatment of Disease n vacuo, of which the followingis a full,clear, and exact description, reference being had to the accompanyingdrawing, making part of 4this specification, in which- Figures 1, 2, and3 represent each a sectional elevation, the two former as applied andpracticed in connection `with the depurator or apparatus patented toFrink, and the latter with the Hadlield apparatus, which has an elasticopen-face piece instead of a head-shield, as in the apparatus of Friuli.

This invention relates to certain newcombinations of oldelements,whereby plain or medicated vapor or spray may be administeredto the patient under treatin ent, partially or wholly 1n vacuum.

This invention also relates to the process of administering plain ormedicated vapor or spray to the patient under treatment, and eitherpartially or wholly inclosed in an airtight case or receiver, andemploying the ordinary atomizer or the common inhaler, using water ormedicated liquid from which to produce the vapor or the spray.

In Fig. l of the drawing we have represented an ordinary atomizerarranged with-in the airti ghtcase. Here the liquid-receiver B standsupon a shelf or bracket, and the draft-tube a extends from near thebottom of the receiver B upward to near the center of the breathingtubeb, which breathing-tube takes the place of the blast-tube or blow-tubeof the atomizer.

A little inside of the draft-tube an d centrally with its upper end is atrumpet-mouthed spraydirecting tube or mouth-piece, a, suitablysupported, say, by a brace, d.

The breathing-tube or blow-tube b may be provided with a valve, h, toregulate the blast of air or steam through the pipe, either of which, orboth combined, are intended to be the motor or operating agent to drawthe liq-` uid from the receiver B and blow it into spray over the topend of the draft-tube into and through the mouth-piece or spray-directoru to the mouth lof the patient, who may hold his head at a greater orlesser distance from the end of the spray-tube, and thereby receive andinhale the spray at any reasonable temperature.

It will be understood that while the spray is being thus administered tothe patient, and` generally before the spray is admitted,consid erableair is pumped out or drawn from the air-tight case or depurator A, sothatthe patient may receive or inhale the spray while in vacuum, theeffect of which is much more satisfactory and benelicial to the patientthan when administered by any former process.

In Fig. 3 we have represented the atomizer on the outside of thedepurator known as the Hadfield apparatus,7 wherein the face of thepatient is exposed.

1 In this apparatus considerable of the air is also exhausted or drawnout from the depurator before the steam or air is admitted through v thevalve-furnished blow-tube b, and the effect produced by this combinedapparatus is intended to be the same as in the apparatus rst described,the principal difference being the combination of the atomizer with andupon the outside of a depurator where the face of the patient isexposed, instead of 4on the inside, as in that rst described.

In Fig. 2 we have represented a common inhaler in combination with thedepurator, as patented by Frink. In this apparatus the liquid-holder Ois partly filled, either with water or with some kind of medicatedliquid, and

generally the latter, which may be cool or suitably heated, as theoccasion may require; and

the heat may be imparted by alamp, D,.placed beneath the liquid-holder,or by steam let in through a pipe, f, to the annular space c of a tankor vessel inclosing the liquid-holder, all as clearly shown in Fig. 2 ofthe drawing. In this apparatus the inhaling-tube Ey enters the top ofthe liquid-receiver, as usual, and eX- tends upward on a curve, or bentback, where it joins onto the breathing-tube b of the depurator or ifthe latter tube is of suicient internal capacity the inhaling-tube maypass directly through it; but we prefer connecting the inhaling-tubewith the breathing-tube, as this admits of the application of astop-valve, c', just inside of the depurator, and conven- 2 nasce ien t,andoperative by the patient with one hand to open or close the valve andadmit or stop the inhalation at his pleasure. The other hand of thepatient may hold the mouth-piece g, connected With the breathing-tube b,generally by a flexible tube.

In the use of the last-described apparatus, instead of heating themedicated or other liquid, as before described, and instead of admittingair to supply the patient with means of and as 'gradually vaporizing andincreasing the volume of vapor to any desired degree.

p Instead ot' Water or medicated liquid, herbs or roots or any othersubstance having suitable medicinal properties may be placed in theliquid-holder C, and soaked or saturated or otherwise suitably prepared,and the patient inhale from these instead of from the liquid.

In the use of' the combined apparatus shown in Fig. 2, considerable ofthe air is exhausted from the depurator, and a l suitable vacuum createdand maintained While the patient is under treatment; and this rendersthe action of inhaling exceedingly easy and Without any effort; and theresult is the same in the apparatusshown inz either of the other.figures. In f'act, the medicated or other inhalations are forced intothe lungs, especially in the apparatus shown in Fig. 2, and such forcedinhalations or respirations will reach or penetrate and ll all, ornearly all, the air cells or tubes or air-passages of the lungs, many ofwhich cannotv be filled .by ordinary breathing, and when theseinhalations are suitably charged with medicinal properties Well known tothe medical faculty or to medical practitioners, .the result will behighly beneficial to the patient.

Our said invention is designed and intended for the treatment ofdiseases ofthe throat, chest,

and lungs, f'or catarrh in the head, and for variousother difficulties,in the successful treatment of' which We have been eminently suc- Wedisclaim a simple inhaling or breathing vtube as patented to Frink, July26, 1870.

t We claim as our invention- 1. rlhe combination, with a depurator, of'an apparatus to supply the patient m vacuo medicaments in the form ot'Vapor or fluid, operating in the manner and for the purpose specified.

. 2. A valve combined with the inductingtube of' the depurator.
